"Early Show" contributing correspondent Taryn Winter Brill got a chance to sit down with Aniston to talk about the movie -- and all things Aniston.
The film has generated its share of controversy.
Conservative talk show host Bill O'Reilly slammed the actress in a recent broadcast, saying, "She's throwing a message out to 12-year-olds and 13-year-olds that, 'Hey, you don't need a guy. You don't need a dad. Dad, ah, you know."'
But Aniston thought long and hard about the message she was sending before deciding to take on the role of Cassie.
"I just love how this movie kind of just talks about what's happening in our society and how we've evolved and how many choices and options we have as women these days," she said.
Would Aniston ever consider going this route -- the "Cassie route" so to speak?
"You never know! I don't know what's going to happen when I leave this room," she replied.
Aniston concurs that she looks for roles she can identify with on a personal level. "Well sure, I think that's really the only way you can really kind of have a connection with something and portray it," she said. "I also want to look for that reality, a-la "The Breakup" or "Marley and Me" -- movies that were rooted in reality. I've been there. I've had a dog die, I've had a best friend who was secretly in love with me."
It must be hard for any man to be friends with the beautiful leading lady.
"So you're OK with being friends with a man who is interested in you?" Brill asked.
"I know so many people who are in that situation, and I think it's just not talked about. Because the friendship is more important," Aniston responded.
One female friendship she cherishes is her relationship with legendary entertainer Barbara Streisand. In September's issue of Harpers Bazaar, Aniston got into full character, and played tribute to the original "Funny Girl."
"I happened to meet her one night at a party, and we sort of became friends and actually, I told Harpers Bazaar, I asked them and pitched the idea and they loved it. She loved it, too, and it was just like, 'It seems like fun and I've never done something like that before,"' Aniston gushed.
Growing up, Aniston idolized the legendary singer.
"I did, I loved her," she said. "There's something about that voice that just kind of, I get addicted to."
Speaking of songs, a lot of people want to know what's on Jennifer Aniston's iPod!
"I do love '70s rock. I dare to say. I do love old you know, old Journey and Aerosmith and Boston, but also I love Lady Gaga," she revealed.
And with that, Brill put on her poker face, and challenged Hollywood's favorite leading lady to a little game.
A lightning round -- 10 questions she called "10 with Jen."
"Oh god, I suck at these," Aniston admitted. "I don't know - I feel very nervous and extremely pressured right at this moment."
1) Salty or sweet?
2) Beach or pool?
"That's a tough toss up"
3) Yoga or pilates?
4) Curly or straight?
5) Bikini or one piece?
6)Heels or flats?
7) Cats or dogs?
8) Night owl or morning person?
9) Tea or coffee?
10) Fries or a baked potato?
"The Switch" opens in theaters today.
